AGS American Glass Services Acquires Mark Industries to Expand Operations in Chicago Area

AGS American Glass Services Acquires Mark Industries

In a strategic move to enhance its position in the competitive glazing market, AGS American Glass Services (AGS), a subsidiary of The Sterling Group Foundation Fund, has successfully acquired Mark Industries, a commercial glazing contractor located in Elgin, Illinois. This acquisition represents a significant step for AGS as it aims to expand its footprint throughout the Chicago metropolitan area.

Mark Industries has built a solid reputation over the years for its expertise in the fabrication and installation of commercial glass systems catering to various sectors, including warehouse, office, and retail installations. The company’s strength lies in its in-house fabrication capabilities and a long-tenured glazier workforce known for delivering high-quality project execution. The existing relationships Mark Industries has developed with customers in the greater Chicago area will prove valuable as AGS continues to integrate operations and enhance service delivery in this vital market.

Josh Cunningham, the owner and President of Mark Industries, will remain with AGS following the acquisition, continuing his leadership role within the company. This continuity is essential for maintaining existing customer relationships and ensuring a seamless transition post-acquisition. Cunningham’s experience and knowledge will help in steering the company towards growth and efficiency under the AGS umbrella.

The acquisition allows AGS to not only increase its market share but also positions it strategically with its East Moline operations. With these locations now in close proximity, AGS is better equipped to efficiently serve clients across northern Illinois, paving the way for improved service delivery and expanded operational capabilities.

Founded in July 2025, AGS launched its operations through investments in Omni Glass & Paint and East Moline Glass, establishing a robust portfolio aimed at leading the commercial glazing and coatings market throughout the Midwest. The consolidation of AGS's ownership of multiple established businesses has birthed a powerful platform that now includes Arrow Glass, Elite Glass & Metal, Cedar Rapids Glass Company, and the newly acquired Mark Industries. As one of the largest glazing contractors in the Midwest, AGS continues to target strategic growth in new and existing markets.

With approximately 500 employees across ten locations and a history that extends over 65 years, AGS is poised to take a leadership role in not only commercial glass installation but also in paint and coating services, tempered glass distribution, and glass products tailored for specialty vehicles. The company's capabilities, bolstered by in-house fabrication, underscore its commitment to scalable growth and meeting diverse customer needs.

In light of this acquisition, AGS is further investing in infrastructure improvements and centralized services aimed at enhancing its operating efficiencies. By focusing on expansion through acquisitions and bolstering its existing operations, AGS is determined to strengthen its position within the Midwest glazing market.

With a vision of being a top-tier glazing platform across the United States, AGS’s acquisition of Mark Industries marks a pivotal moment in its journey, reflecting the firm’s commitment to growth and operational excellence. As the landscape of commercial glazing evolves, AGS stands ready to capitalize on opportunities that lie ahead while ensuring that quality service remains at the forefront of its operations.
